Calculating the intensity of a microwave involves understanding the concept of power density, also known as power flux density (PFD). Power density is the amount of power per unit area that is radiated or received by an antenna. In the case of a microwave transceiver, it refers to the power density of the microwave radiation at a given distance from the transmitter.
To calculate the power density (intensity) of a microwave from the current, voltage, and distance between the transmitter and receiver, you'll need some additional information:
Transmitting Antenna Gain (Gt): This parameter represents how well the transmitter focuses its energy in a specific direction. It is given in decibels (dB) and is a measure of the directivity of the antenna.
Wavelength (λ) of the microwave: The wavelength of the microwave is necessary to convert between power density and power.
With these parameters, you can use the following formula to calculate the power density (S) at a certain distance (r) from the transmitting antenna:
